RECORDING-LOCK.

SPECIFICATION forming part of Letters Patent N0. 735,034, dated July 28,1903. Application filed August 29, 1902. Serial No. 121,499. (No model.)

To all 1071 0772, it may concern:

Be it known that I, ALLEN DE VILBISS, Jr., a citizen of the UnitedStates, and a resident of Columbus, Franklin county, State of Ohio,

have invented certain new and useful Improvements in Recording-Locks;and my preferred manner of carrying out the invention is set forth inthe following full, clear, and exact description, terminating withclaims [0 particularly specifying the novelty.

This invention'relatesto recorders, more especially to that class knownas workmens time-operated recording-machines, such as are actuated byany one of several keys;

and the object of the same is to produce a recording-lock which eachtime it is opened will furnish a correct record of the hour and minutewhen such opening occurred and a correctrecord of the key which wasemployed. Experience has taught the proprietors of some establishmentswhose employees have keys of their own that on occasions some personpossessing such a key may return after hours, enter the establishmentwith per haps foul intent, remain therein for some time, and thendepart, and heretofore the employer who may reside elsewhere has nomeans of knowing what has occurred unless he should later discover someof the results, The object of the present invention is todevise a lockfor the main or front door of the establishment which shall contain arecording mechanism of such construction thatit will make a record ofthe time when such en- 5 try into the building was effected and theexact key which was used and will make another record when the lock wasagain opened to permit exit from the building, thus furnishing theemployer with knowledge which will serve as a check upon those whoshould have his key. It is obvious that an almost endless combination ofmechanisms can be employed for carrying out this general idea, and Idesire it distinctly understood that the present specification anddrawings are intended to set forth only one of many constructions andarrangements which might be used.

Herein I have employed broad terms, es-

5 pecially in the claims, and in the specification and drawings I haveset forth specifically the constructionof the elements broadly coveredby those terms merely inorder to explain one form of each elementand onearrangement of the whole which occurs to me 5-; at this time.

To this end the invention consists in'a lock of'any type which willanswer, with which is combined and associated a recording mechanism ofthe type hereinafter set forth.

In the accompanying drawings, Figure I is a centrallongitudinal sectionof the lock with the bolt shot. Fig. II is a similar section wit-l thebolt retracted, showing in dotted lines how the actuating-lever of thepaperfeed is sprung over the key-bit. Fig. III is an elevation of thelock with the front plate removed, showing the bolt as shot andillustrating more particularly the key-indicator, which is located tothis side of and does not appear in the two previous views. This figurealso shows a modification of the paperfeed, which is perhaps a=betterconstruction than that elsewhereillustrated. Fig. IV is a transversesection on the line IV IV of Fig. III. Fig. V is a diagrammatic viewillustrating the action of the key-bit on the keyindicatorsetting-lever. g

The lock proper comprises acasing l, having a keyhole 2, in which isintended to work a key having a shank 3 and a bit 4, as shown. Thelatter enters a notch 5 in the bolt 6, which in this case' has a beveledfront end 7 and is thrown normally'forward by aspring 8, as usual inwhat'are known as springlooks. It is not necessary tdiIIus-trate otherfeatures of the lock, and itwill be clear that the latter need notnecessarily be ofthe spring type. However, the term bolt used herein isintended to designate that part of the go look which engages with akeeper to lock the door closed.

The recording mechanism as a whole is actuated through the movement ofthe key, the latter in the present constructionacting directly oncertain parts and acting indirectly through the bolt .on other parts,all as more fully described below; but it is the insertion and movementof the key in. the lock which produces therecord. In the pres- 10c entcase the latter comprises a time-record and a key-record, the formerindicating the time when the key was used on each occasion of its useand the latter indicating which key was used. In the present instancethe keys are dilferentiated from each other by slight differences in theradial lengths of their bits; but it will be understood that differencesin the longitudinal lengths thereof comprises an hour-wheel 10 and aminutewheel 11, connected by gearing 12 and so mounted that their upperfaces stand flush beneath the paper. These wheels are of the drum typeand have characters 13 on their peripheries. In the present case theseare printing characters or type rising above the drum-faces; but theycould be dies which would indent or puncture the recordstrip describedbelow. Preferably Within the hourwheel is located a clock mechanismadapted to be wound by the spindle 14, which mechanism is so arranged asto turn the minutewheel one-twelfth of a revolution every five minutesand to turn the hour-wheel onetwelfth of a revolution every hour; butany arrangement will answer which will cause this time-indicator to havea movement (preferably intermittent) so that itsuppermost charactersshall constantly indicate the exact or approximate time.

' The key-indicator herein shown comprises a wheel 20, also of the drumtype and having characters 23 on its periphery, which may be letters orwords, to indicate the various keys employed. This drum may Well bemounted on the shaft of the larger time-wheel, and it may have a hub 21with a roughened or notched periphery, against which presses the tip ofa retaining-spring 22 for the purpose of steadying the wheel while inuse. Its hub,

possibly at the other side of its body, may be provided with a pinion24, engaged by a rackbar 25, pivotally supported at one end of a lever26, whose other end is pivoted in a bracket 27, the lever being drawninto normal position against a stop 28 by a spring 29. This lever standsin the present instance above the keyhole, as best seen in Fig. V, andalong its lower edge has an active face which is practically straightfrom 30 to 31, where it merges into a neutral face extending from 31 to32 and struck on an arc corresponding substantially with that describedby the outer end of the key-bit 4. As the key turns in the direction ofthe arrow in this view it first strikes the point 30, and as it travelsto the point 31 it raises the settinglever, which raises the rack-bar,which rotates the key-indicator and brings uppermost thereon a certaincharacter corresponding with the length of the key-bit and the height towhich the active face was raised. Next the bit strikes the edge of thenotch 5 in the bolt 6 and performs the work described below. Reachingthe point 31, which has now been raised to the dotted lines, the bittravels around the neutral face of thelever 26 to the point 32. Duringthis travel it does no work, and the retaining-spring 22 holds thekey-indicator steady.

The inker 39 may be of any type; but in the present instance it issimply a roller mounted on a suitable bearing and faced with felt or anequivalent cushion, which bears constantly on the characters of thewheels passing beneath it, the felt being moistened with ink from timeto time. If the indicators are of the die form, which impress or cut therecord-strips, the inker will be omitted.

The record -feed in the present instance comprises a drum 40, hereinshown as drawing a strip of paper or the like off of a roll 42, which isheld by a tension-spring 43, although this record might be cloth, metal,or anything suitable for receiving the impression of the characters onthe indicators. Any suitable means may be employed for turning the drum.In Figs. I and II, I have shown a le= ver 44, having an actuating-pawl45 engaging a ratchet 46 on the end of the drum (4? being aretaining-pawl) and the tip 48 of this lever stands in the path of thekey-bit. By preference it has a spring-actuated knuckle= joint 49 whereit is connected with the body of the lever, so as to permit the key tomove in the other direction. The entire lever is of such a length and sopivoted that its tip slides oif the key-bit, as shown in dotted lines inFig. II, just as the bit moves the bolt to make the impression, asdescribed below. A

slight modification of these features and a simpler construction isshown in Fig. III. Herein the actuating-pawl 450 is pivoted directly tnthe bolt 6 and is thrown up against the ratchet by a spring 490. Theshape and length of this pawl must be such that the feed of the recordwill be accomplished and finished before the bolt has been movedsufficiently to do the printing, as described below.

The recorder in the present instance is a printing mechanism, because itemploys a platen adapted to press a paper strip against type which havebeen inked; but it is clear that this recorder could be a complementarydie or a cushion or anything whose function was to impress or imprintthe characters of the indicators on or into the record-strip. In fact,the face of the recorder could itself receive the imprint, so that thepaper might be omitted. As shown herein, 50 is a platen carried by oneend of an arm 51, which is intermediately pivoted, as at 52. Pivoted tothe other end of this arm is a push-bar 53, herein shown as hangingtherefrom and resting normally against a stop 54. This bar may have anantifriction device, such as a roller 55, at its lower end. Said endstands above the lower extremity of a cam 56, rising from the bolt. Itfollows that when the latter is thrown inward the active face of the camraises the push-bar, depresses the platen, and

makes a record of those characters on the indicator which were at thatmoment uppermost, and as the bolt is again shot its lower end or heelswings the lower end of the pushbar outward, so that it drops back tothe position shown and rear y for subsequent use.

The indicators are herein shown as wheels, which form, I presume, is thepreferred one, yet I do not limit myself to such a construction.Itisclearthatanindependently-driven time-indicator will not be useful asan indicator without some printing mechanism used in conjunction unlessmechanism be used to stop its rotation when the bolt is moved. Not onlyis this idea broadly old, but such a device could then indicate only onepoint of time, and subsequent employees might enter the building withoutmaking a record or giving any indication. It will also be clear that thekey-indicator is not useful without the printing mechanism so long asthe spring 29 is employed, which returns it to the starting-point afterthe withdrawal of the key; but by omitting this spring one indication(and only one) could be expressed without the use of the printingmechanism. Hence to make these wheels indicators in a true sense I mayprovide their side faces with letters or figures, as shown at 100 inFig. III, and have openings 101 in the lock-casing, through which thesecan be seen. I lay no claim to this feature, however, but have describedit to show one of a great variety of amplifications and modifications towhich the broad idea of this invention is susceptible without departingfrom its spirit. I might add that it is not inconsistent with theinvention to omit either indicator and use only the other, to use both,as shown, or to employ other indicators for other purposes when desired.

While I have described the invention as useful in the lock which closesthe main door of an establishment, it is clear that the machine could beused as aworkmens time-rec- 0rd to check his arrival in the morning andhis departure in the evening.
